When a script sends a form it uses the current user as the sender and
appends the server name on the end e.g. apache (at mark) ns3.mydomain.net

Sendmail then does a quick check on all messages that it sends to ensure
that the sender is real and not spoofed.

So, check your form script to make sure it's setting the sender of the
message as well as the recipient.  This isn't totally required but it's good
practice and makes for a more professional e-mail too :-)

Ensure the sender e.g. query (at mark) example.com has a user or an alias to a user of
query under the example.com site.

I hope that makes sense.
